LOL!! :lol::lol::lol:

Rich, I will stand by what I said to you on the phone in that I will help to get you up & running :) It has been confirmed more than once the compression figures are spot on, bearings in good condition, no bore damage, no noises etc etc. It is important it's clear to all that read this that I haven't sold you a broken engine. This thread is in the public domain and is an ongoing concern. There have been posts made alluding to it being my fault, mentioning "warranty" in one of them. I didn't fit the engine, so I cannot be responsible for installation issues such as oil leaks & failing turbos. It certainly wasn't delivered to you in that condition. I'm quite concerned that all this has happened to you, but I didn't fit the engine or have any say in who did, so I must stand by the fact I sold an engine with good compression, no leaks & no smoke, confirmed by myself and subsequently others. Any oil leak or severe smoke should have been diagnosed on the road test. I have a specific engine builder & installer I use, in that situation if something goes awry, it is much more simple to sort out. It also wasn't sold with the front of it covered in rust. It looks as if it has been dragged out of a lake :( Another problem is that issues have been discussed over the phone that have not been revealed on this thread, so not everyone is privy to the full scenario. It's not my place to disclose these, but it's in my interest I'm not unfairly judged when it is so easy to point the finger on the Internet, as it still reads "Bad engine sold as good" to me :) Anyways, like I said from the start, I will still help with this when I get chance. Time is indeed the main issue, but you did say you weren't in a rush at all on the phone when I said it would be roughly mid July. I think Mark is aiming to get to you earlier, but don't quote me on that. You may indeed have to incur costs in order to get your car up & running, are you willing to risk your other turbos being up to scratch after sitting around? Even without a major oil leak, they may still fail if the seals have dried out. It's best to get them rebuilt. As it's been run so low on oil, it may have damaged the bearings, so it would be good to have those fully checked & replaced for peace of mind as well. Gaskets & seals where required too, of course. Basically, a full inspection. Unfortunately, after the engine & turbos were sat around for 4+ months in a place where the front pulley has become unusable due to rust, everything should have been fully stripped down, inspected, then refurbished or replaced where necessary :(

No blowby & 180psi compression means it's a good engine. I think it's only fair to stress that. Oil feed line broken -> insubstantial oil for turbo bearings -> failed turbo. I'd expect that the turbo has about 5mm longitudinal shaft play. I'd also expect that the turbo would have ran dry almost immediately, destroying the bearings & seals, hence the smoke as soon as the car was driven and minimal boost produced. Were there any installation issues? There wasn't a massive oil leak from when I sold the engine. Let's hope the lack of oil has not caused any premature bearing wear and the damage is confined to the turbocharger.

No bore damage. Failed ringlands letting that much oil in would have smooth vertical sections and it would be impossible for the oil to seal in 180psi with such damage. There would also be monumental amounts of blowby from 3 cylinders (I'm assuming there isn't since it's not been mentioned). It looks a bit like failed ringlands, but all the compression tests & lack of bore damage suggest otherwise.

Now this is the correct way round to do a guessing thread :laugh:

Honestly, I'm stumped. The amount of oil that has come off those plugs is unreal. I bought a Skyline with a broken RB26DETT, 45psi on cyl 6 from a shattered ringland and it didn't smoke like that or foul the plug that bad. Still made 1.4 bar and pulled (and smoked) like a train. It breathed constantly heavy out of the breathers, smokey just like the exhaust. Here, there's only one bank that's the problem, but I still can't see how a turbo would push that much oil into the opposing cylinders. If it's stem seals, it would smoke blue first thing. It would also likely smoke on the overrun if they're really bad. That white/grey smoke is vapourised oil, collapsed turbo bearings as bad as I've ever seen. If the engine was ingesting that much oil, I doubt it would run, and there would be a huge amount of blue smoke, too. If it was rings, it would smoke all the time. On the video it's only when revved, and there's no blue at all (from what I can see).

^^^ So it's game on, you read it here folks :clap:

I'm OK with running my own car like this and reporting the results (it's my guinea pig daily, and sees a fair bit of drag strip action as well), but it's different when mapping a customer's car. It's all very well someone saying "push it", but if something goes wrong, guess who gets the blame and bad reputation... Unless it's a fully-documented no-holds barred push for the stars (and it's clear to everyone in Internet World you have a specific target and need to run 1.5+ bar), I'm not going to be able to map your standard turbo'd car to 500bhp, there aren't enough modifications for it IMO and it's not worth the potential nightmare if something goes wrong. You're going to need to run to the very limit of the turbos, consider race fuel and WI, run twin widebands & aftermarket knock monitoring, monitor IATs, consider EGTs as well. I'm comfortable doing this in my own car, but I can't expect someone else to in theirs, so there needs to be a safety margin involved. Bear in mind I've just mapped a stock engine to ******* safely with zero issues, and have pushed my own stock 2L 3SGTE to 487bhp, I just think this is a bad idea to have these kinds of expectations. No problem whatsoever with mapping your car when it's ready (been looking forward to it as it's a great project idea), but it's only going to make whatever it makes. Safely :thumbup1: It's also worth bearing in mind that the mapping work that has gone into my own dual intake single MAF set up running 1.4-1.5 bar daily on stock turbos for 18 months is a great deal more than £250. Most likely 10 times that. Plus fuel. Plus dyno time. Plus Santa Pod entry. And so on!

Injectors will never stop me, I can simply increase the fuel pressure & remap the car. There was loads of fuelling available at 456bhp, my set up on the day was maxed. 456bhp & 482lbft means lots of boost from little turbos. I've been too busy to work on my own car, but it's engine breathing, not fuel delivery that is the obstacle to overcome :) I've only got one PM of yours yet to answer I think.

Near side rear turbo seal is one of the issues IMO.

Ask if they will drop the off side downpipe quickly.

Apparently, upon inspection, the big end bearings looked to have been changed recently as well.

Hello & welcome. Nice Zed :)

Afraid not, said over the phone I had just dismissed them as they were spot-on :( I personally think that the off side turbo has failed on the exhaust side. The amount of oil that came from just the plugs on the off side bank (cyls 2, 4 & 6), plus the fact that the threads are soaked with oil, would suggest a huge oil leak on that side. The turbo will have failed due to the seals drying out I'd expect.

No damage to the bores, the garage has had a borescope down the bores...

The thing is, it's a problem on only one bank as far as oil fouling & losing cylinders is concerned isn't it? The driver's side bank is fine, right?

I once had a Sapphire Cosworth that chucked oil over the cars behind me accompanied by masses of blue & white smoke. The little end bearings were shot plus the head had been skimmed too much. The pistons were hitting the head it was that bad. Still went like the clappers, but bought a new engine before it inevitably went bang. --------------------------- Rich: The amount of rust that are on the pulleys & tensioner can only have developed from being left exposed to the elements at some point. It was removed on Sunday night/Monday morning, and delivered to you on the same Monday afternooon IIRC. It had been parked before then maybe 2 weeks since I had bought the car, with the belts in place. Rust on the near-side actuator rod as well. You'll have to report back the compression test results. If they are OK, see if there is oil residue in the turbo elbows. Get a borescope down the plug holes. Just seen the video. That's a huge amount of smoke. The plug looks wet with oil in the pics, but hard to tell. Could be a combination of leaking turbo seals & piston ring failure. That blue thing is a t-piece. But I kept all the vac lines & t-pieces for use with the HDi EBC. I'm tight like that.

It's also missing the cambelt covers (IIRC), the injector rails, injectors, coil packs etc. I forwarded the CAS on to Rich about a week after he bought the engine in January, so that should have been with it, too. It was definitely not sold in that condition. The only explanation for the rust is that it has been left outside for some time. dicky96: Is the white smoke sweet-smelling or acrid?

What on Earth? The engine was NEVER in that state when it was removed. Where's the plenum? Why are all the pulleys rusty? It should have been road-tested once fitted, so why weren't the issues discovered before he got the car back? Something very odd is going on here.

That engine was mint when it was removed from Ken's car. Zero smoke & silent. :confused1: I have no idea what's happened here, but I thought it was supposed to have been checked over before being fitted* :( I can't remember the compression test results, but there was nothing amiss at all. I think I looked back through Ken's posts before buying his car to see if there were any revealing issues, but can't recall anything. *In addition to it having been sold as a good working engine of course

Hahaha, pretty sure I remember saying "I knew there'd be nothing wrong with the base map.... There is a reason why I'm kind of busy....

The fuel leak is a new one!

It's always the tuner that gets the blame. It's rarely the tuner that is to blame :thumbup1:

More than stock :)
